This is driving me nuts.
I have SQL files set up to open Toad Data Point in Windows.
If I don't have an existing instance of TDP running, double-clicking a SQL file in my File Explorer will open up the file just fine. However, if I've already got an instance of TDP running, nothing will happen. I either have to use File-->Open from TDP, or I can drag the file from File Explorer into an existing editor window, and then a new editor window will open with the file.
Any ideas as to why double-clicking won't just open a new Editor window in my TDP instance? I've never had this problem before...
